Chikungunya Fever Outbreak — The Threat of Mosquito-Borne Diseases and Preventive Measures
Recently, the southern region of China has experienced outbreaks of mosquito-borne diseases such as Chikungunya Fever and dengue fever, which pose a serious threat to public health. According to reports from local health authorities, the number of cases continues to rise, especially during the humid season when mosquito breeding accelerates, further exacerbating the spread of these diseases. Mosquitoes, as the primary vectors, not only impact the quality of life for local residents but also place significant pressure on the healthcare system. Therefore, understanding these diseases and their preventive measures is particularly important.
Causes and Transmission of Chikungunya Fever
Chikungunya fever is caused by the Chikungunya virus, a small RNA virus belonging to the Togaviridae family. The virus is primarily transmitted by the Aedes aegypti and Aedes albopictus mosquitoes, which are particularly common in southern China. The geographical distribution of the Chikungunya virus is widespread, and with the effects of global climate change and human activities, the range of the virus continues to expand, putting more regions at risk for outbreaks.
Symptoms and Diagnosis of Chikungunya Fever
Common symptoms of Chikungunya fever include high fever, severe joint pain, muscle pain, headache, nausea, fatigue, and rash. These symptoms typically appear 2 to 12 days after infection and last for about a week; however, some patients may experience prolonged joint pain affecting daily life. In terms of diagnosis, blood tests are the primary method, but due to the similarity of symptoms with other diseases (such as dengue fever and influenza), the diagnostic process presents certain challenges, requiring the professional judgment and experience of healthcare workers.
Preventive Measures for Mosquito-Borne Diseases
To effectively prevent Chikungunya fever, personal protective measures are crucial. It is recommended to wear long-sleeved clothing and use insect repellents containing DEET, which can significantly reduce the risk of bites. Additionally, community-level mosquito control should not be overlooked; eliminating standing water and other mosquito breeding sites, such as water in plant pots and discarded tires, is an effective way to reduce mosquito reproduction. Using air purifiers to improve indoor environments and reduce mosquito entry is also an effective preventive measure, especially during active mosquito seasons.
Points to Consider When Choosing Insect Repellents
To effectively prevent mosquitoes, consider using well-reviewed insect repellents available on the market. These repellents and mosquito lamps typically use light waves, scents, aerodynamics, or a combination of these methods to attract, eliminate, or repel mosquitoes. Here are detailed explanations of the attracting methods and considerations when choosing:
- Light Wave Attraction: Many mosquito lamps use ultraviolet (UV) or specific wavelengths of light (such as 365-395nm) to attract mosquitoes, as female mosquitoes are phototropic to specific light waves.
- Scent Attraction: Some mosquito lamps simulate human scents (such as carbon dioxide or lactic acid) to attract mosquitoes.
- Aerodynamics: Some devices utilize fans to create vortex airflow, drawing mosquitoes into trapping devices. Such devices are suitable for indoor and outdoor use, but attention should be paid to whether the fan noise affects sleep or daily activities.
- Combination of Multiple Methods: Efficient devices often combine multiple attracting methods. When selecting such devices, it is advisable to prioritize models that integrate various attracting methods, as a single method may not effectively address different mosquito species or environmental conditions.
How to choose insect repellents or mosquito lamps:
- Select Based on Usage Scenario: For indoor use, choose low-noise devices (e.g., less than 35dB) without chemicals. For outdoor use, consider devices with larger coverage and durability.
- Check the Effectiveness of Attracting Methods: Devices combining light waves, scents, and aerodynamics typically perform better.
- Safety and Environmental Friendliness: Choose products without chemicals and that meet photobiological safety standards (e.g., EN62471) to avoid impacts on humans or pets.
- Ease of Use and Maintenance: Prioritize devices that are easy to clean (e.g., with removable insect collection trays) or equipped with timing functions.
- Coverage Area and Power: Ensure the device's coverage area is suitable for the intended space.

The threat of Chikungunya fever and other mosquito-borne diseases to public health cannot be ignored. With climate change and urbanization, the risk of transmission for these diseases will persist. It is urged that individuals and society strengthen prevention and control measures, including raising awareness about mosquito prevention and improving environmental hygiene, thereby jointly protecting public health and reducing disease transmission. Only through collective effort can we effectively respond to this challenge and ensure the health and safety of society.
